Earlier today there was discussion of the FluxEngine[1], due to it's newly added Mac 800k disk read/support (OK, it had read for a while, but now it can both read <i>and</i> write).<p>What I love about the FluxEngine is that it is so simple - no custom PCBs, just a single PSOC development board with a single set of soldered header pins.<p>Not saying that the other alternatives are bad - it's great to have competition. For several years it seemed that KryoFlux would be the sole dominant USB floppy controller, nice to see there's a range of options available.<p>Edit: seems as though FluxEngine may gain support for using GreaseWeazle hardware[2] at some point, which would be neat!<p>[1] <a href="https://news.ycombinator.com/item?id=25656283" rel="nofollow">https://news.ycombinator.com/item?id=25656283</a><p>[2] <a href="https://news.ycombinator.com/item?id=25675381" rel="nofollow">https://news.ycombinator.com/item?id=25675381</a>
I recently demonstrated a 3.5 and 5.25 in solution based on greaseweasle if you are interested to see how it looks like: <a href="https://youtu.be/7C9adUKbLj8" rel="nofollow">https://youtu.be/7C9adUKbLj8</a>
